The LS30 comes with 3 different EQ modes. The first mode (1 beep) is the default normal mode. This mode is custom crafted by LucidSound to provide an ideal frequency response for gaming. The second mode (2 beeps) is the Bass Boost mode. This mode increases the low frequency sounds to give gunshots, crashes, and explosions more impact. The third mode (3 beeps) is the Treble Boost mode. This mode enhances subtle high frequency sounds such as footsteps and guns reloading.
